Main factor affecting climate in the northeastern part of Kenya:

The main factor affecting the climate in the northeastern part of Kenya is the region's proximity to the equator and its position in the rain shadow of the Aberdare and Mount Kenya mountain ranges. This results in a semi-arid to arid climate with low and erratic rainfall, high temperatures, and frequent droughts. The region also experiences strong seasonal winds, known as the "Harmattan," which bring dry and dusty conditions from the Sahara Desert. These factors contribute to the harsh and challenging climate conditions in the northeastern part of Kenya.
